The effect of temperature on photosynthesis 1

Without the greenhouse effect, life on this planet would probably not exist as the average temperature of the Earth would be a chilly -18 degrees Celsius, rather than the present 15 degrees Celsius....

Water temperature has direct and indirect effects on nearly all aspects of stream ecology

Within matter, atoms and their constituents are constantly in motion. The arrangement and motion of atoms vary in characteristic ways, depending on the substance and its current state (e.g., solid, liquid). Chemical composition, temperature, and pressure affect such arrangements and motions of atoms, as well as the ways in which they interact. Under a given set of conditions, the state and some properties (e.g., density, elasticity, viscosity) are the same for different bulk quantities of a substance, whereas other properties (e.g., volume, mass) provide measures of the size of the sample at hand.

Environmental effects on photosynthesis. I. Temperature

Once the matter is buried at about 450 meters, the temperature and pressure begin to cause the rearrangement of matter.

The factors that effect the germination of seeds are: · Temperature · Acid rain · Oxygen · Water I will just see what effect does the acid rain have on germination of seeds.

Society has tended to address the short term effects of climatic changes that influence the global temperatures within the life span of present generations.

Temperature response of photosynthesis in C3, C4, and …

2) Partially full milk jug with hot water, put the cap on tightly, and let it sit for one hour to see the effect of a slow change in temperature....

Energy can also be transferred from place to place by electric currents. Heating is another process for transferring energy. Heat transfer occurs when two objects or systems are at different temperatures. Energy moves out of higher temperature objects and into lower temperature ones, cooling the former and heating the latter. This transfer happens in three different ways—by conduction within solids, by the flow of liquid or gas (convection), and by radiation, which can travel across space. Even when a system is isolated (such as Earth in space), energy is continually being transferred into and out of it by radiation. The processes underlying convection and conduction can be understood in terms of models of the possible motions of particles in matter.

Stability and instability in any system depend on the balance of competing effects. A steady state of a complex system can be maintained through a set of feedback mechanisms, but changes in conditions can move the system out of its range of stability (e.g., homeostasis breaks down at too high or too low a temperature). With no energy inputs, a system starting out in an unstable state will continue to change until it reaches a stable configuration (e.g., the temperatures of hot and cold objects in contact). Viewed at a given scale, stable systems may appear static or dynamic. Conditions and properties of the objects within a system affect the rates of energy transfer and thus how fast or slowly a process occurs (e.g., heat conduction, the diffusion of particles in a fluid).

This process to happen efficiently it requires the presence of light, water carbon dioxide, chlorophyll and enzymes.

Graph Showing Effect of Temperature on Rate of ..

An issue of major concern is the possible effect of the burning of fossil fuels and other contributers to the in the atmosphere. The action of carbon dioxide and other in trapping infrared radiation is called the . It may measurably increase the overall average temperature of the Earth, which could have disastrous consequences. Sometimes the effects of the greenhouse effect are stated in terms of the of the Earth, the overall average reflection coefficient.

# 43 Effect of Carbon Dioxide on the Rate of Photosynthesis

Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast moving molecules collide with other fast moving enzymes causing them to react....

#42 Effect of Temperature on the Rate of Photosynthesis

To attempt to quantify the effects of greenhouse gases on the global temperature, climatologists use the "" of the current atmospheric content of these gases.

The Effect of Light on Photosynthesis :: Papers - …

This process is also affected by the temperature surrounding the plant (the species of plant we experimented with, pond weed, photosynthesised best at around 20 degrees centigrade.) Light, temperature & CO2 are known as limiting factors, and each is as important as the next in photosynthes...

is the effect of temperature as the lights ..

A limiting factor is a factor that controls a process. Light intensity, temperature and carbon dioxide concentration are all factors which can control the rate of photosynthesis. Usually, only one of these factors will be the limiting factor in a plant at a certain time. This is the factor which is the furthest from its optimum level at a particular point in time. If we change the limiting factor the rate of photosynthesis will change but changes to the other factors will have no effect on the rate. If the levels of the limiting factor increase so that this factor is no longer the furthest from its optimum level, the limiting factor will change to the factor which is at that point in time, the furthest from its optimum level. For example, at night the limiting factor is likely to be the light intensity as this will be the furthest from its optimum level. During the day, the limiting factor is likely to switch to the temperature or the carbon dioxide concentration as the light intensity increases.
